Thanks the blessing of the Lord

Deuteronomy 26:1-19
Bring the firstfruits of the soil that the Lord have given to us. Your and the Levites and the aliens among you shall rejoice in all the good thing the Lord have given to you and your household.
The third year is the year of the tithe, you shall give it to the Levite, the aliens, the fatherless and the widow so that they may ear in your towns and be satisfied.
Pray to the Lord and say to the Lord:"I have obeyed the Lord my God; I have done everything you commanded me. Look down from heaven, your holy dwelling place, and bless your people Israel and the land you have given us as you have promised on oath to our forefathers."
Why?
This is a commandment of the Lord-set aside the first fruit and tenth from our produce to the Lord.
The fruits of the soil is blessing from the Lord, so we should thank the Lord, and share it with Levites and aliens and fatherless and widows.
Tithe is our obligation to the Lord, and it is for the living of Levites, they are the servant of the Lord.
The Lord has everything, doesn't lack anything, but when we devote these, setting side a tenth of all produce, it shows our heart is reverent to the Lord and we may share it with needed peoples, the Lord will bless us.
How?
I do set aside the tenth of my income and it is before the tax deduction, for all I have is from the Lord, I'd rather take the ninth of the produce,it is my portion from the Lord.
Thank you your blessing to me, my Lord.
